Abstract: Dans le contexte de l'invention, un récepteur récupère des données de symboles OFDM (multiplexage par division de fréquence orthogonale), les symboles OFDM incluant une pluralité de signaux de sous-porteuses. Certains des signaux de sous-porteuses acheminent des symboles données et certains des signaux de sous-porteuses acheminent des symboles pilotes, les symboles pilotes comprenant des symboles pilotes diffus et des symboles pilotes continus. Les symboles pilotes continus sont distribués au travers des signaux de sous-porteuses conformément à un modèle de symboles pilotes continus, tandis que les symboles pilotes diffus sont distribués au travers des signaux de sous-porteuses conformément à un modèle de symboles pilotes diffus. Le récepteur comprend un démodulateur configuré pour détecter un signal représentant les symboles OFDM et pour générer une version numérique échantillonnée des symboles OFDM dans le domaine temporel. Un processeur de transformée de Fourier est configuré pour recevoir la version numérique en domaine temporel des symboles OFDM et pour former une version en domaine fréquence des symboles OFDM, à partir de quoi les sous-porteuses acheminant des symboles pilotes et les sous-porteuses acheminant des symboles données peuvent être récupérées. Un détecteur est configuré pour récupérer les symboles données des sous-porteuses acheminant des données des symboles OFDM et pour récupérer les symboles pilotes des sous-porteuses acheminant des pilotes des symboles OFDM conformément au modèle de symboles pilotes diffus et au modèle de symboles pilotes continus. Le modèle de symboles pilotes diffus est un modèle parmi une pluralité de modèles de symboles pilotes diffus, et le modèle de symboles pilotes continus est indépendant du modèle de symboles pilotes diffus. Le détecteur comprend une mémoire configurée pour stocker un modèle maître de pilotes continus et un processeur configuré pour détecter le nombre de signaux de sous-porteuses dans la pluralité de signaux de sous-porteuses et pour dériver le modèle de pilotes continus d'un modèle maître de pilotes basé sur le nombre de symboles de sous-porteuses.

Abstract: A coupling for joining pipe elements end to end has a unitary band surrounding a central space for receiving the pipe elements. Ends of the band are in facing relation. Adjustable connection members are positioned at each end of the band for drawing the ends toward each other and deforming the band. Arcuate ribs are positioned lengthwise along opposite sides of the band. The ribs are separated from one another by gaps between the ribs. In their undeformed state, each rib has an arcuate surface with a radius of curvature equal to the radius of curvature of the outer surface of the pipe elements which they engage. When the band is deformed the ribs clamp against the outer surface of the pipe elements to effect the joint.

Abstract: An example method of calibrating a downhole tool includes stimulating a known current through a power circuit provided in the downhole tool, the power circuit extending between and communicably coupling a power source and a load. A conductor magnetic field is generated as the known current flows through the power circuit and the conductor magnetic field is detectable by a magnetic sensor included in the downhole tool to obtain sample measurements of Earth's magnetic field. A magnitude of the conductor magnetic field is then measured to obtain a measured value for the conductor magnetic field, and a relationship between the known current and the measured value is determined to calculate a correction factor for the sample measurements based on the relationship. A computer in the downhole tool is then programmed to apply the correction factor to the sample measurements in response to operational currents measured in the power circuit during operation.
